A combined impression technique for a partial implant-supported fixed-detachable restoration.
A passive fit between osseointegrated implants and the prosthesis supported by them is crucial to the correct distribution of the stress exerted on the implants. The accuracy of the impression procedure in duplicating the exact position of the implant abutment is one of the main contributors to passive fit. An impression technique is presented whereby the dentate and edentulous parts are duplicated in elastomeric material, providing both the flexibility needed to remove the impression and the required accuracy. Subsequent duplication of the implant zone with plaster, without removal of the tray, affords a high degree of accuracy.
